Late to the party here...
Grew up in Catonsville, live in Carroll Co. now.
Had AGC membership years ago, let it lapse when fees doubled to buy the 'buffer' property behind the 100 range. Renewed it at a gun show couple years back when my son became interested in shooting. Last straw, a 20 dollar fee to bring him or any guest to shoot with me.
Bangsteel, DO IT! Take the Friday/Saturday course. Dan and his son, Forrest are fantastic teachers! No pressure, laid back class. They now do 'Range Days' on Fridays for 80 bucks, 40 more and you can try for the mile plate and the 2200 yard plate. I'm going back!
The Hap Baker Range in the Westminster land fill is cool. Avoid the place from October to December when the deer hunter sight in crowd can make wait times a few hours to get one of the ten benches.
Anybody wanting to try PRS events? Mason/Dixon in Mayberrry, Md. run a great event about 6 times a year there. No pressure, helpful shooters get you started right.
What I find most rewarding? Look into Guardian long range events. Match fees are tax deductible and for charity. Have done two so far at Frontline Defense in North Carolina. Paul Smith runs a first class range ! Huge prize table. I won a Nightforce scope with only a 10 ticket purchase. Guardian does about 6 events all over the United States every year. Check out their website.
